LOOM -SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 558,570, dated April 21, 1896.

Application filed September 11, 1893. Renewed November 29, 1895. Serial No. 670,539. (No model) Patented in England December 7,1892, No. 22,423.

To all whom it may concern.-

Be it known that we, WILLIAM SARGENTSON and JAMES GILBERT, citizens of the United Kingdom of Great Britain and Ireland, residing at Hadfield, in the county of Derby, Eng land, have invented certain new and useful Improvements in Loom-Shuttles, (patented in Great Britain December 7, 1892, No. 22,423,) of which the following is a specification.

This invention relates to shuttles for use in looms; and its object is to provide a simple and economical construction whereby such shuttles may be easily threaded without their efficiencybeing affected when in use and without suction.

In carrying this invention into practice a slot or groove is formed in that part of the shuttle extending from the open part toward the tip, and a second slot or groove is formed which extends from the first and passes obliquely over the shuttle and-terminates at the delivery-eye. Vithin this slot there is placed a wire suitably bent and coiled so as to form two eyes or thread-guides, one of which is at the junction of the grooves and the other at the delivery-eye.

IVe will more particularly describe our said invention with reference to the accompanying drawings, in which Figure 1 shows a perspective view of a front part of a shuttle having our improved threading device applied thereto. Fig. 2 is a sectional elevation of the same, and Fig. 3 an inverted sectional view showing the manner of application of the device. Fig. 4 is a side elevation, and Fig. 5 a plan of the threading device detached from the shuttle.

In each of the figures in which the parts are represented, A is the body of the shuttle; O, the tongue; D, the cop thereon.

In the form of the threading device illustrated in the drawings a suitable length of brass or steel wire is screwed at one end and bent to the form shown by Figs. 4 and 5 and so as to produce the two eyes or thread-guides E E, of which E will come at the junction of the before-mentioned slots and E at the de- The longitudinal slot F is formed from the hollow of the shuttle to a point near the tip, and the diagonal slot G connects the delivery-eye with the longitudinal slot, as shown in Fig. 1. This slot is also shown in Fig. 3 at its junction with the longitudinal slot. At the delivery-eye a hole is bored for the reception of the threadguide E, which lies flush with the side of the shuttle.

In order to enable the threading device illustrated by Figs. 4 and 5 to be fitted to the shuttle, two additional temporary slots K K are made. Of these the slot K is made in the bottom of the shuttle for the passage of thc screwed end of the device and K in the side of the shuttle for the passage of the threadguide. The device is applied as illustrated by Fig. 3, where its first position is shown by the full lines. From this position the device is pushed along the slots toward the tip of the shuttle until it finally occupies the position shown by the dotted lines. The side slot K, so far as it is unoccupied by the thread-guide, is then filled up. At the outer part of the portion of the slot K which is finally occupied by the end of the screwed stem a recess is formed for its nut H. A collar or nut I is also arranged on the screwed part to act as'a stop.

To thread the shuttle, the end of the weft from the cop is taken between the finger and thumb, passed along the longitudinal slot F, returned around the point B of the device, passed into and down the diagonal slot G, by which the thread is brought down and into the thread-guide E. The weft is now outside the delivery-eye, and in order to make it enter this eye E it is only necessary to pass the weft around it until it enters, the eye being constructed similarly to the well-known pigtail thread-guide, but flatter, as shown. It will be understood that for the purpose of enabling the weft to enter the eye E there must be a little clearance around it for the movement of the yarn.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is- A shuttle provided with a longitudinal slotand a transverse slot leading from the delivcry-eye of the shuttle to the longitudinal slot, in combination with a threading device located in the longitudinal slot consisting of a Wire bent upon itself at a sharp angle and having one end fixed to the shuttle and the other bent spirally to form two guides or eyes, one of said guides or eyes being located at the junction of the slots and the other in the transverse slot.

In testimony that We claim the foregoing as our invention we have signed our names,

in presence of two witnesses, this 17th day of August, 1893. V
